Thinking of having laser eye surgery - your questions answered

If you are thinking about laser eye surgery, you are not alone. It is one of the most common elective procedures in the UK, and most patients are extremely satisfied with the result. Still, it is normal to have questions before committing to treatment. Here are the answers to the questions I hear most often in my clinics.

Does laser eye surgery hurt?

No. The procedure itself is not painful because anaesthetic drops are used to numb the surface of the eye. You may feel a sensation of pressure when the surgeon creates the flap or applies the laser, but this is brief. After the procedure, some patients experience mild grittiness, watering or a feeling similar to having an eyelash in the eye for a few hours. Simple pain relief usually helps.

How long does the procedure take?

The laser treatment itself is very fast, often less than a minute for each eye. Including preparation, checks and aftercare, you will usually be in the treatment room for 10 to 15 minutes. The actual time the laser is reshaping the cornea is usually under a minute per eye.

Will I be awake during the surgery?

Yes, you are awake. You need to be able to follow simple instructions and keep your eye still. Your eye is numbed with drops, and you are not looking at the laser itself. Most patients are surprised by how calm and quick the experience is. A mild sedative can be offered if you are anxious.

How soon will I be able to see?

Most patients notice an improvement in vision within hours of LASIK or SMILE. By the next day, many people can drive and work as normal. With surface treatments such as LASEK or TransPRK, recovery is slower because the surface of the eye needs to heal, and vision can take several days to a week to become clear.

When can I drive and go back to work?

For LASIK and SMILE, most people can return to work and drive within 24 to 48 hours, provided their vision meets the legal standard. For LASEK, this may take four to seven days. Your surgeon will confirm when it is safe for you, and you should not drive until you have been cleared.

Is laser eye surgery safe?

Laser eye surgery is very safe when performed on suitable patients by experienced surgeons using modern technology. Serious complications are rare. Like any surgery, there are risks, including infection, inflammation, dry eye and night vision symptoms. A thorough assessment helps identify patients who are more likely to have a complication.

What are the main risks?

The most common side effects are temporary dry eye, glare and halos around lights at night. These usually improve over the first few months. More serious problems, such as infection or an weak flap, are rare. The risk is higher in patients with thin corneas, very high prescriptions, dry eyes or certain corneal shapes, which is why the assessment is so important.

Is everyone suitable for laser eye surgery?

No. Laser eye surgery is not suitable for everyone. Your cornea must be thick enough and healthy enough, your prescription must be stable, and your eyes must be free of significant disease. Some people are better suited to alternatives such as implantable collamer lenses (ICLs) or refractive lens exchange. The only way to know for sure is to have a full assessment.

What happens if I blink or move my eye?

Your eye is held open gently during the procedure, so blinking is not possible. Modern lasers also track the eye's movements thousands of times per second. If your eye moves too far, the laser stops automatically. You do not need to worry about keeping your eye perfectly still.

How long does the result last?

The laser correction is permanent. The reshaped cornea does not grow back. However, your eyes will continue to age naturally. Most people enjoy excellent vision for many years, but presbyopia from the mid-40s and cataracts later in life can affect vision regardless of whether you have had laser surgery. Enhancements are possible in some cases if small changes occur.

How much does laser eye surgery cost?

Costs vary depending on the clinic, the technology used and the complexity of your prescription. In the UK, prices typically range from around £1,500 to £3,000 per eye. Be cautious of very low advertised prices, as the final cost often depends on your prescription and the type of treatment recommended. Ask for a fully inclusive quote that covers surgery, aftercare and any enhancements within a defined period.

Next steps

If you are considering laser eye surgery, the best next step is a comprehensive, consultant-led assessment. Bring your current glasses or contact lens prescription, a list of any medications, and be prepared to discuss your lifestyle and expectations. A good surgeon will tell you honestly whether laser surgery is right for you, and explain the alternatives if it is not.
